Title: Brake operating device with modulator

Abstract: A braking power modulator is coupled to the brake lever of a brakeoperating device for easy adjustment and viewing. The braking powermodulator is preferably adjustable to provide different braking powers fordifferent riders or different road conditions. The braking power modulatorbasically includes a mounting member, a brake lever, a biasing member, amodulating member and an adjusting member. The mounting member is adaptedto be coupled to a handlebar of a bicycle, and has a cable passageway witha first abutment and a second abutment. The brake lever is pivotallycoupled to the mounting member, and has a cable attachment portion. Thebiasing member is disposed in the cable passageway, and has first andsecond portions with the first portion of the biasing member beingoperatively coupled to the first abutment. The modulating member with theadjusting member coupled thereto is movably arranged within the cablepassageway and operatively biased against the second abutment by thesecond portion of the biasing member. The adjusting member is movablyarranged along the modulating member and biased toward the second abutmentof the mounting member. A cable tensioning member is adjustably coupled tothe modulating member. The biasing member is disposed in the tubularportion of the brake lever under a preloaded state with a pre-setcompression force. The adjusting member engages the biasing member tochange the pre-set compression force of the biasing member withoutchanging the predetermined modulator stroke of the second blockingportion.
